Etymology The first part of the genus name is chosen in honour of the syllid expert Guillermo San Martin. The second part is taken from Exogonita, a name proposed by Hartman and Fauchald (1971) for an abyssal taxon originally also characterised by absence of prostomial antennae and presence of two pairs of cirri on the first segment, but later synonymised with Exogone Oersted [details]

Classification ""Guillermogonita gen. nov ,is difficult to assign to any of the traditionally recognised subfamilies of Syllidae. Overall it resembles the Exogoninae Langerhans, 1879, but the palps are separated as in some members of Syllinae Grube,1850, whereas the compound chaetae are very similar to those in some members of the hesionid genus Podarke Ehlers, 1864."
